Abstract
Disclosed herein is an automatic pressure adjustment pressing jig that includes a reaction plate and a driving plate facing each other, and a plurality of pressing plates arranged to enable linear movement between the reaction plate and the driving plate, and pouch batteries inserted between the pressing plates are pressurized by a pressure applied as the driving plate moves toward the reaction plate, and the driving plate retracts in predetermined units by a torque-responsive adjustment device that automatically attenuates increased torque in response to a torque increase corresponding to increased pressure caused by expansion of the pressurized pouch batteries.
